A meta-analysis of diabetes risk prediction models applied to prediabetes screening.

AIM: To provide a systematic overview of diabetes risk prediction models used for prediabetes screening to promote primary prevention of diabetes. METHODS: The Cochrane, PubMed, Embase, Web of Science and China National Knowledge Infrastructure (CNKI) databases were searched for a comprehensive search period of 30 August 30, 2023, and studies involving diabetes prediction models for screening prediabetes risk were included in the search. The Quality Assessment Checklist for Diagnostic Studies (QUADAS-2) tool was used for risk of bias assessment and Stata and R software were used to pool model effect sizes. RESULTS: A total of 29 375 articles were screened, and finally 20 models from 24 studies were included in the systematic review. The most common predictors were age, body mass index, family history of diabetes, history of hypertension, and physical activity. Regarding the indicators of model prediction performance, discrimination and calibration were only reported in 79.2% and 4.2% of studies, respectively, resulting in significant heterogeneity in model prediction results, which may be related to differences between model predictor combinations and lack of important methodological information. CONCLUSIONS: Numerous models are used to predict diabetes, and as there is an association between prediabetes and diabetes, researchers have also used such models for screening the prediabetic population. Although it is a new clinical practice to explore, differences in glycaemic metabolic profiles, potential complications, and methods of intervention between the two populations cannot be ignored, and such differences have led to poor validity and accuracy of the models. Therefore, there is no recommended optimal model, and it is not recommended to use existing models for risk identification in alternative populations; future studies should focus on improving the clinical relevance and predictive performance of existing models.

Analysis of the changing trend of economic burden of patients with chronic diseases under the Integrated Medical and Health Service System.

BACKGROUND: Integrating medical resources is one of the explorations of medical mechanism reform to meet the needs of whole-cycle health management and is an important initiative in the current round of China's healthcare system reform. 2015 saw the construction of county medical communities to promote the balanced layout of medical resources, which opened a new exploration of the construction of an integrated healthcare service system in China. 2017 saw the promotion of the pilot construction of compact county medical communities in Zhejiang Province, China. OBJECTIVE: From the perspective of alleviating the financial burden on those in need of health services, the characteristics of chronic disease patients' access to health care and the composition and changing curve of the medical cost burden are analyzed to provide a basis for the construction path of an integrated health care service system. METHODS: A retrospective cohort study was conducted to select 5739 permanent residents who met the inclusion and exclusion criteria in Z town, H city, Zhejiang province. This population's health insurance utilization data from 2015 to 2018 were retrieved, and their average annual costs, cost composition, and health insurance payments were analyzed. RESULTS: The average annual growth rates of medical insurance and out-of-pocket costs before and after the implementation of the Medical Community were 12.85% and 9.72%, respectively. The increase narrowed significantly after the construction of the Medical Community, with the ringgit growth rate dropping to 2.73% in 2018. The top three medical expenses that accounted for the highest percentage were drug, consultation, and treatment fees. The frequency of visits to primary health care consulting hospitals has increased yearly. CONCLUSIONS: By implementing various measures to strengthen the grassroots level, patients' choice of primary care has increased year by year in the early stages of the construction of the Medical Community. From the perspective of cost control, strengthening the regulation of drugs and tests and restricting the use of high-value consumables can further reduce medical costs and ease their financial burden.

NudCD1 as a prognostic marker in colorectal cancer and its role in the upregulation of cellular spindle assembly checkpoint genes and LIS1 pathways.

OBJECTIVE: To investigate the role of NudCD1 in spindle assembly checkpoint regulation and in the prognosis of colorectal cancer.  METHODS: Immunohistochemical staining was used to detect in situ expression of NudCD1 in 100 colorectal cancer tissue samples. A chi-square test was used to analyse the correlation between the NudCD1 protein expression level of the cancer tissues and clinicopathological features. The Kaplan-Meier survival analysis was used to assess the correlation between the NudCD1 mRNA expression and the three-year survival of patients with colorectal cancer. The impact of NudCD1 on the development of colorectal cancer and the underlying molecular mechanisms were assessed by flow cytometry cell cycle and apoptosis assays after lentiviral overexpression of NudCD1 in two colorectal cancer cell lines. Quantitative real-time PCR was used to assess mRNA expression of the cellular spindle assembly checkpoint genes BUB1, BUBR1, MAD1, CDC20 and MPS1, as well as the downstream genes LIS1, DYNC1H1, and DYNLL1 in the NudC/LIS1/dynein pathway. RESULTS: Compared with normal intestinal tissue (8.00% with high expression), the expression of NudCD1 protein in colorectal cancer tissue was significantly higher (58.00% with high expression, P < 0.01). In addition, expression of NudCD1 significantly correlated with the degree of tumour differentiation and the TNM staging (P < 0.01), as well as the depth of invasion of the primary tumour and lymph node metastasis (P < 0.05). However, there was no correlation with gender, age, tumour site, gross type, tumour size or distant metastasis. The Kaplan-Meier survival analysis showed that patients with high NudCD1 expression in colorectal cancer tissues had a significantly shorter survival time than those with low expression of NudCD1 (P < 0.01). Compared with the transfection of the empty vector, colon cancer HT-29 cells with overexpressed NudCD1 had significantly increased mRNA levels of BUBR1, MPS1 and LIS1. The DNA synthesis phase (S phase) was significantly shorter in cells overexpressing NudCD1 than in the control group (43.83% ± 1.57%, P < 0.05), while there was no difference in apoptosis in the two groups. CONCLUSION: NudCD1 can serve as a valuable prognostic marker for colorectal cancer. It may be involved in the regulation of spindle-assembly checkpoint-gene expression and the LIS1 pathway of colorectal cancer cells.

A Single-Center Retrospective Study to Compare the Efficacy and Safety of Modified FOLFIRINOX with S-1 as Adjuvant Chemotherapy in 71 Patients with Resected Pancreatic Carcinoma.

BACKGROUND Studies are ongoing to determine the optimal adjuvant chemotherapy (ACT) for resected pancreatic carcinoma (PC). FOLFIRINOX is a chemotherapy regimen including oxaliplatin, irinotecan, leucovorin, and 5-fluorouracil (5-FU). S-1 is a fluoropyrimidine derivative widely used as ACT for gastrointestinal malignancy. This single-center retrospective study aimed to compare the efficacy and safety of modified FOLFIRINOX (mFOLFIRINOX) with S-1 as ACT for resected PC. MATERIAL AND METHODS A total of 71 patients with PC who accepted ACT after R0 resection between February 2016 and January 2019 were enrolled in this retrospective study. Among these patients, 34 received mFOLFIRINOX regimen chemotherapy (mFFX group), while 37 received S-1 monochemotherapy (S-1 group). The mFOLFIRINOX regimen included oxaliplatin 65 mg/m², leucovorin 400 mg/m², irinotecan 150 mg/m², 5-FU 400 mg/m², and continuous 5-FU 2400 mg/m² (for 46 h), in a 2-week schedule. The S-1 monochemotherapy (80-120 mg/day according to body surface area [BSA], in 2 divided doses for 2 week) was administrated every 3 weeks. We followed up these patients and analyzed the relapse-free survival (RFS), overall survival (OS), and chemotherapy-induced adverse events (AEs). RESULTS The mFFX group demonstrated a markedly higher 3-year RFS (P=0.0332) and OS (P=0.0346) than the S-1 group. Patients in the mFFX group experienced significantly more common and severe thrombocytopenia (P=0.0372), fatigue (P=0.0226), nausea/vomiting (P=0.0337), and diarrhea (P=0.0018). No chemotherapy-induced death was documented. CONCLUSIONS This retrospective study indicated that if dose adjustment and adverse events management are properly administrated, mFOLFIRINOX regimen chemotherapy could result in an improved survival compared with S-1 monochemotherapy for resected PC.

Effect of Shengbai Decoction on Chemotherapy-Induced Myelosuppression and Survival of Gastric Cancer Patients After Radical Resection: A Retrospective Study.

BACKGROUND Myelosuppression is one of the most common chemotherapy-induced adverse events and results in a series of clinical symptoms. This study aimed to evaluate the effect of Shengbai decoction (SD) on chemotherapy-induced myelosuppression and survival of gastric cancer (GC) patients after radical resection. MATERIAL AND METHODS We retrospectively analyzed data from 115 patients with stage II-III GC who underwent adjuvant chemotherapy after radical resection between May 2015 and June 2017 in our hospital. Among these patients, 57 received Shengbai decoction along with adjuvant chemotherapy (SD group), while 58 received adjuvant chemotherapy alone (control group). Medical records, including adverse events, the treatment completion rate of adjuvant chemotherapy, 3-year overall survival (OS), and 3-year recurrence-free survival (RFS), were compared. RESULTS Patient characteristics did not differ significantly between the 2 groups. No adverse events related to Shengbai decoction were reported in the SD group. Patients in the SD group had less neutropenia (P=0.0430), thrombocytopenia (P=0.0323), and anemia (P=0.0497). The SD group had a significantly lower probability of dose reduction (P=0.0448). The completion rate of adjuvant chemotherapy of the SD group was considerably higher than that of the control group (P=0.0398). The SD group had a significantly better 3-year RFS (P=0.0369) and 3-year OS (P=0.0455) than the control group. CONCLUSIONS Shengbai decoction effectively improved postoperative survival of patients with GC by alleviating chemotherapy-induced myelosuppression and improving the completion rate of adjuvant chemotherapy.

Adjuvant albumin-bound paclitaxel combined with S-1 vs. oxaliplatin combined with capecitabine after D2 gastrectomy in patients with stage III gastric adenocarcinoma: a phase III multicenter, open-label, randomized controlled clinical trial protocol.

BACKGROUND: Surgery is the only treatment option for operable gastric cancer. The CLASSIC and ACTS-GC studies showed that the 5-year overall survival (OS) of patients with stage III gastric cancer undergoing D2 gastrectomy is still very low. Whether adjuvant nanoparticle albumin-bound paclitaxel (nab-paclitaxel) combined chemotherapy is more effective than the XELOX standard adjuvant chemotherapy in patients with stage III gastric cancer has not been confirmed. METHODS: This is a multicenter, open-label, phase III clinical study. In this trial, 616 patients with locally advanced stage III gastric cancer that underwent curative D2 radical surgery and achieved R0 are planned to be included. Patients will be randomized 1:1 to nab-paclitaxel combined with S-1 (AS) vs. oxaliplatin combined with capecitabine (XELOX). XELOX group: Patients assigned to the XELOX group received eight 3-week cycles of oral capecitabine (1000 mg/m2) twice daily on days 1-14 of each cycle plus intravenous oxaliplatin 130 mg/m2 on day 1 of each cycle. AS group: AS group received eight 3-week cycles of oral S-1 (80-120 mg) (< 1.25 m2, 40 mg; 1.25 to < 1.5 m2, 50 mg; and > 1.5 m2, 60 mg) twice daily on days 1-14 plus intravenous nab-paclitaxel 120 mg/m2 on days 1 and 8 of each cycle. The primary endpoint was the 3-year disease-free survival (3-year-DFS) defined as the time from randomisation to the time of recurrence of the original gastric cancer, development of a new gastric cancer, or death from any cause. The secondary endpoints were the overall survival, (defined as the time from the date of randomisation to date of death from any cause) and safety (any adverse event). DISCUSSION: Compared with previous studies, this study includes nab-paclitaxel based on S-1 adjuvant chemotherapy, which is expected to achieve better efficacy and lower toxicity than the standard treatment. This study is the first clinical study to evaluate the safety and efficacy of nab-paclitaxel combined with S-1 in patients with stage III gastric cancer after D2 radical resection. TRIAL REGISTRATION: This clinical trial has been registered with ClinicalTrials.gov, registration number: NCT04135781 , on October 20th, 2019.

Hypoxia promotes the migration and invasion of human hepatocarcinoma cells through the HIF-1α-IL-8-Akt axis.

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death worldwide. The 5-year survival rate remains low despite considerable research into treatments of HCC, including surgery, radiotherapy and chemotherapy. Many mechanisms within HCC still require investigation, including the influence of hypoxia, which has a crucial role in many cancers and is associated with metastasis. Hypoxia inducible factor-1α (HIF-1α) is known to regulate the expression of many chemokines, including interleukin-8 (IL-8), which is associated with tumor metastasis. Although many studies have reported that HIF-1α is associated with HCC migration and invasion, the underlying mechanisms remain unknown. METHODS: The expression level of HIF-1α was determined in HCC cells. The correlation of IL-8 and HIF-1α expressions was assessed via knockdown of HIF-1α. HCC cells were also used to assess the influence of HIF-1α on HCC cell migration and invasion. LY294002, an inhibitor of the Akt pathway, was used to confirm the associated signaling pathways. RESULTS: We observed a significant attenuation of cell migration and invasion after silencing of HIF-1α. Exogenously expressing IL-8 restored migration and invasion. Akt was found to be involved in this process. CONCLUSION: Hypoxia promotes HCC cell migration and invasion through the HIF-1α-IL-8-Akt axis.

HIF-1α promotes the migration and invasion of hepatocellular carcinoma cells via the IL-8-NF-κB axis.

BACKGROUND: Hypoxia plays a critical role in many cancers. Hypoxia inducible factor-1α (HIF-1α) is an important mediator of the hypoxia response. It regulates the expression of various chemokines involved in tumor growth, angiogenesis and metastasis but the associated pathway needs further investigation. METHODS: The expression level of HIF-1α was determined in hepatocellular carcinoma (HCC) cells. The correlation of interleukin-8 (IL-8) and HIF-1α was assessed by knocking down HIF-1α. These cells were also used to assess its influence on HCC cell migration and invasion was checked. Pyrrolidinedithiocarbamate (PDTC), an inhibitor of NF-κB, was used to confirm the associated signaling pathway. RESULTS: HIF-1α was significantly expressed in HCC cells and found to promote HCC cell migration and invasion in an IL-8-dependent manner. NF-κB was confirmed to be involved in the process. CONCLUSIONS: HIF-1α promotes HCC cell migration and invasion by modulating IL-8 via the NF-κB pathway.

Mast cell specific immunological biomarkers and metabolic syndrome among middle-aged and older Chinese adults.

The main aim of this study is to explore whether these mast cell specific immunological biomarkers [immunoglobulin E (IgE), chymase and tryptase] is an independent risk factor of MetS and whether the combined action of these biomarkers increased the associations with MetS. Three mast cell-specific immunological biomarkers were measured using enzyme linked immunosorbent assay (ELISA). One-way analysis of covariance and logistic regression models were used for analyzing the associations between immunological biomarkers with MetS. A total of 340 participants, 82 (24.1%) individuals had diabetes mellitus, 31 (9.1%) had MetS (without diabetes mellitus) and 110 had MetS plus diabetes mellitus. After adjusting by multivariable (age, gender, smoking, and family history for hypertension), compared with no diabetes mellitus or MetS group (reference group), hs-CRP was associated with diabetes mellitus [OR (odds ratio): 2.29 (1.15-4.57, 95% CI (confidence interval), p=0.019] and MetS plus diabetes mellitus [OR: 2.20 (1.05-4.61, 95% CI), p=0.036], IgE was associated with MetS plus diabetes mellitus [OR: 2.38 (1.13-5.02, 95% CI), p=0.023]. After adjusting by multivariable, compared with reference group, most of combined elevated inflammatory or immunological biomarkers were significantly associated with diabetes mellitus or MetS with or without diabetes mellitus. Patients with established diabetes mellitus or MetS had different inflammatory or immunological cytokine profile (such as hs-CRP, IgE, chymase, tryptase), which indicated that there is an alteration in the function of the immune system in diabetes mellitus or MetS patient. But these results are requested to be further demonstrated for large sample population-based cohort study.

Early nasogastric feeding versus parenteral nutrition in severe acute pancreatitis: A retrospective study.

OBJECTIVE: To compare the efficacy and safety of early nasogastric enteral nutrition (EN) with total parenteral nutrition (TPN) in patients with severe acute pancreatitis (SAP). METHODS: From July 2008 to July 2014,185 patients with SAP admitted to our centre were enrolled in this retrospective study. They were divided into EN group (n=89) and TPN group (n=96) based on the nutrition support modes. Patients in EN group received nasogastric EN support, while patients in TPN group received TPN support within 72 hours of disease onset. The medical records were reviewed and clinical factors were retrospectively analyzed. RESULTS: There were no significant differences in baseline characteristics between two groups. EN group had significantly lower incidence of pancreatic infections (P=0.0333) and extrapancreatic infections (P=0.0431). Significantly shorter hospital stay (P=0.0355) and intensive-care stay (P=0.0313) were found in EN group. TPN group was found to have significantly greater incidence of multiple organ dysfunction syndrome (MODS) (P=0.0338) and mortality (P=0.0382). Moreover, the incidence of hyperglycemia was significantly higher in TPN group (P=0.0454). CONCLUSIONS: Early nasogastric EN was feasible and significantly decreased the incidence of infectious complications as well as the frequency of MODS and mortality caused by SAP.

Eukaryotic translation initiation factor 5A2 (eIF5A2) regulates chemoresistance in colorectal cancer through epithelial mesenchymal transition.

BACKGROUND: Chemoresistance is a major obstacle to successful chemotherapy for colorectal cancer. Eukaryotic translation initiation factor 5A2 (eIF5A2), one of the two isoforms in the eIF5A family, has been reported to be a new oncogene in many types of human cancer. In the present study, we aimed to investigate whether eIF5A2 was involved in the chemoresistance to doxorubicin in colorectal cancer. METHODS: Cell viability was measured by CCK-8 assay with or without doxorubicin treatment. Protein expression was detected by western blot. Tumor cells were transfected with eIF5A2 siRNA or plasmid encoding eIF5A2 to down- or up regulate the expression of eIF5A2. RESULTS: We found that eIF5A2-negtive colon cancer cells (HCT116 and HT29) were more sensitive to doxorubicin compare with the eIF5A2-positive cells (LOVO and SW480). Downregulation of eIF5A2 in LOVO and SW480 cells enhanced the chemosensitivity to doxorubicin. On the contrary, overexpression of eIF5A2 reduced doxorubicin sensitivity in colon cancer cells. In addition, eIF5A2 knockdown increased the protein level of E-cadherin and reduced vimentin expression in LOVO and SW480 cells. Meanwhile, upregulation of eIF5A2 potentiated epithelial mesenchymal transition (EMT) in colon cancer cells. Moreover, blockade of EMT with Twist siRNA abolished eIF5A2-regulated chemoresistance in colon cancer cells. CONCLUSION: Our present study demonstrated that eIF5A2 promoted the chemoresistance to doxorubicin via regulation of EMT in colon cancer cells. Therefore, eIF5A2 inhibition may be a new potential strategy for the reversal of drug resistance in colorectal cancer therapy.

High Blood Glucose Levels Correlate with Tumor Malignancy in Colorectal Cancer Patients.

BACKGROUND Research shows that type 2 diabetes mellitus (T2DM) affects the risk and prognosis of colorectal cancer (CRC). Here, we conducted a retrospective study to investigate whether the clinicopathological features of CRC patients correlate with their blood glucose levels. MATERIAL AND METHODS We enrolled 391 CRC patients hospitalized in our center between 2008 and 2013. Data of their first fasting plasma glucose (FPG) and 2-h postprandial glucose (2hPPG) level after admission, their clinicopathological features, and survival were collected. The correlations between blood glucose level and clinicopathological features were analyzed by Pearson chi-square analysis. Patient survival was analyzed by Kaplan-Meier and Cox-regression analysis. RESULTS There were 116 out of the 391 CRC patients who had high blood glucose level (H-G group, 29.67%), among which 58 (14.83%), 18 (4.60%), and 40 (10.23%) were diabetes mellitus (DM), impaired glucose tolerance (IGT), and impaired fasting glucose (IFG), respectively, while 275 (70.33%) patients had normal glucose level (N-G group). Compared with the N-G group, patients in the H-G group had larger tumor diameters and lower tumor differentiation (p<0.05). A higher ratio of patients in the H-G group also had more advanced TNM staging and more ulcerative CRC gross type (p<0.05). No significant difference was observed in patient overall survival among different glucose groups. No effect of insulin therapy on CRC development and patient survival was observed. CONCLUSIONS Blood glucose level in CRC patients correlates significantly with local tumor malignancy, but no significant effect on distant metastasis and patient overall survival was observed.

RENAL PROTECTIVE EFFECT AND CLINICAL ANALYSIS OF VITAMIN B 6 IN PATIENTS WITH SEPSIS.

ABSTRACT: Objective: To investigate the protective effect and possible mechanisms of vitamin B 6 against renal injury in patients with sepsis. Methods: A total of 128 patients with sepsis who met the entry criteria in multiple centers were randomly divided into experimental (intravenous vitamin B 6 therapy) and control (intravenous 0.9% sodium chloride therapy) groups based on usual care. Clinical data, the inflammatory response indicators interleukin 6 (IL-6), interleukin 8 (IL-8), tumor necrosis factor (TNF-α), and endothelin-1 (ET-1), the oxidative stress response indicators superoxide dismutase, glutathione and malondialdehyde, and renal function (assessed by blood urea nitrogen, serum creatinine, and renal resistance index monitored by ultrasound) were compared between the two groups. Results: After 7 d of treatment, the IL-6, IL-8, TNF-α, and ET-1 levels in the experimental group were significantly lower than those in the control group, the oxidative stress response indicators were significantly improved in the experimental group and the blood urea nitrogen, serum creatinine, and renal resistance index values in the experimental group were significantly lower than those in the control group ( P < 0.05). There was no statistical difference between the two groups in the rate of renal replacement therapy and 28 d mortality ( P > 0.05). However, the intensive care unit length of stay and the total hospitalization expenses in the experimental group were significantly lower than those in the control group ( P < 0.05). Conclusion: The administration of vitamin B 6 in the treatment of patients with sepsis attenuates renal injury, and the mechanism may be related to pyridoxine decreasing the levels of inflammatory mediators and their regulation by redox stress.

Efficacy and Safety of Hepatic Arterial Infusion Therapy with Cinobufacini in Advanced Hepatocellular Carcinoma with Macrovascular Invasion: A Retrospective Cohort Study.

Background: The presence of macrovascular invasion (MVI) is associated with poor prognosis in advanced hepatocellular carcinoma (HCC). This study aims to evaluate the efficacy and safety of Cinobufacini therapy via hepatic arterial infusion (HAI) in advanced HCC patients with MVI. Methods: The clinical records of 130 consecutive patients with unresectable advanced HCC and MVI who had received Cinobufacini or cisplatin plus 5-fluorouracil (CF) treatment via HAI were retrospectively analyzed. The therapeutic efficacy, overall survival (OS), progression-free survival (PFS), and adverse events were compared between the two treatment groups. Results: The Cinobufacini group demonstrated significant curative effects on treatment via HAI compared with the CF group, including the objective response rate (44.9% vs 27.9%, P=0.048), the median OS (14.8 months vs 11.1 months, P=0.010), and the median PFS (10.3 months vs 6.0 months, P=0.006). Result in subgroup analysis of portal vein invasion grade supported the efficacy in Cinobufacini treatment, especially in the median OS of Vp1-2 (18.3 months vs 14.3 months, P=0.043) and Vp3 (15.0 months vs 11.4 months, P=0.046), as well as the median PFS of Vp1-2 (14.8 months vs 10.2 months, P=0.028) and Vp3 (10.8 months vs 6.6 months, P=0.033) compared with CF treatment. Cox proportional hazards model and forest plot analysis of factors confirmed the survival benefit from HAI with Cinobufacini over CF (hazard ratio [HR], 0.61; 95% CI: 0.40-0.91; P=0.010). Multivariable analysis identified portal vein invasion grade (Vp4; HR, 1.78; 95% CI: 1.03-2.16; P=0.032) and AFP (>1000; HR, 1.61; 95% CI: 1.08-1.91; P=0.039) as the independent factors for prognosis. Moreover, the total incidence of adverse events in the Cinobufacini group was significantly lower than in the CF group (60.9% vs 82.0%, P=0.009). Conclusion: Cinobufacini therapy via HAI is a viable strategy for curing advanced HCC with MVI, due to prolonged survival and a superior safety profile.

Hierarchical Architecture Engineering of Branch-Leaf-Shaped Cobalt Phosphosulfide Quantum Dots: Enabling Multi-Dimensional Ion-Transport Channels for High-Efficiency Sodium Storage.

New-fashioned electrode hosts for sodium-ion batteries (SIBs) are elaborately engineered to involve multifunctional active components that can synergistically conquer the critical issues of severe volume deformation and sluggish reaction kinetics of electrodes toward immensely enhanced battery performance. Herein, it is first reported that single-phase CoPS, a new metal phosphosulfide for SIBs, in the form of quantum dots, is successfully introduced into a leaf-shaped conductive carbon nanosheet, which can be further in situ anchored on a 3D interconnected branch-like N-doped carbon nanofiber (N-CNF) to construct a hierarchical branch-leaf-shaped CoPS@C@N-CNF architecture. Both double carbon decorations and ultrafine crystal of the CoPS in-this exquisite architecture hold many significant superiorities, such as favorable train-relaxation, fast interfacial ion-migration, multi-directional migration pathways, and sufficiently exposed Na+ -storage sites. In consequence, the CoPS@C@N-CNF affords remarkable long-cycle durability over 10 000 cycles at 20.0 A g-1 and superior rate capability. Meanwhile, the CoPS@C@N-CNF-based sodium-ion full cell renders the potential proof-of-feasibility for practical applications in consideration of its high durability over a long-term cyclic lifespan with remarkable reversible capacity. Moreover, the phase transformation mechanism of the CoPS@C@N-CNF and fundamental springhead of the enhanced performance are disclosed by in situ X-ray diffraction, ex situ high-resolution TEM, and theoretical calculations.

A study on the effect of using the video teach-back method in continuous nursing care of stroke patients.

Objective: To explore the effect of a video teach-back method on continuous family nursing care of stroke patients. Methods: Stroke patients hospitalized in our hospital between March 2020 and March 2023 who met the inclusion criteria were randomly divided into an intervention group (n = 45), who received routine health education plus video teach-back training of caregivers, and a control group (n = 45), who received routine health education only. The effects on nursing-related variables were compared between the two groups. Results: Total scores representing the caring ability of caregivers in the intervention group increased significantly over time relative to baseline and were higher than those of the control group. Scores representing the care burden of caregivers in the intervention group decreased significantly over time and were lower than those of the control group. Conclusion: The teach-back method combined with video education improves the nursing ability of family caregivers and can improve the self-care ability of stroke patients.

Prognostic value of serum cholinesterase activities in sepsis patients.

BACKGROUND/AIMS: This study aims to explore the prognostic value of Serum cholinesterase (SchE) activity in patients with sepsis. METHODOLOGY: The evaluation variable of APACHE II score was assessed and the SchE concentrations were determined in 359 patients immediately upon admission and 24 hours after admission. All patients were divided into two groups based on their prognosis. The relationships of SchE concentration and APACHE II score with prognosis were analyzed. RESULTS: The SchE activity was significantly higher (p <0.01) and the APACHE II score was significantly lower (p <0.01) in survivors than in non-survivors. The areas under the receiver operating characteristic curve (AUC) were more than 0.9 for both the loss of SchE activity (delta SchE) and the loss of APACHE II score (delta APACHE II) during 24 h in patients admitted 24 h after onset (D1). The AUC for SchE activity and APACHE II were similar in most groups except hepatobiliary infection group. CONCLUSIONS: The SchE activity and APACHE II score were useful for prognosis of septic patients. Although SchE activity was not as powerful as APACHE II in the prognosis of sepsis, dynamic monitoring of SchE and APACHE II had similar value in outcome prediction.

Performance of a prediabetes risk prediction model: A systematic review.

Backgrounds: The prediabetes population is large and easily overlooked because of the lack of obvious symptoms, which can progress to diabetes. Early screening and targeted interventions can substantially reduce the rate of conversion of prediabetes to diabetes. Therefore, this study systematically reviewed prediabetes risk prediction models, performed a summary and quality evaluation, and aimed to recommend the optimal model. Methods: We systematically searched five databases (Cochrane, PubMed, Embase, Web Of Science, and CNKI) for published literature related to prediabetes risk prediction models and excluded preprints, duplicate publications, reviews, editorials, and other studies, with a search time frame of March 01, 2023. Data were categorized and summarized using a standardized data extraction form that extracted data including author; publication date; study design; country; demographic characteristics; assessment tool name; sample size; study type; and model-related indicators. The PROBAST tool was used to assess the risk of bias profile of included studies. Findings: 14 studies with a total of 15 models were eventually included in the systematic review. We found that the most common predictors of models were age, family history of diabetes, gender, history of hypertension, and BMI. Most of the studies (83.3%) had a high risk of bias, mainly related to under-reporting of outcome information and poor methodological design during the development and validation of models. Due to the low quality of included studies, the evidence for predictive validity of the available models is unclear. Interpretation: We should pay attention to the early screening of prediabetes patients and give timely pharmacological and lifestyle interventions. The predictive performance of the existing model is not satisfactory, and the model building process can be standardized and external validation can be added to improve the accuracy of the model in the future.

Butyrate reverses ferroptosis resistance in colorectal cancer by inducing c-Fos-dependent xCT suppression.

Ferroptosis has emerged to be a promising approach in cancer therapies; however, colorectal cancer (CRC) is relatively insensitive to ferroptosis. Exactly how the gut microenvironment impacts the ferroptotic sensitivity of CRC remains unknown. Herein, by performing metabolomics, we discovered that butyrate concentrations were significantly decreased in CRC patients. Butyrate supplementation sensitized CRC mice to ferroptosis induction, showing great in vivo translatability. Particularly, butyrate treatment reduced ferroptotic resistance of cancer stem cells. Mechanistically, butyrate inhibited xCT expression and xCT-dependent glutathione synthesis. Moreover, we identified c-Fos as a novel xCT suppressor, and further elucidated that butyrate induced c-Fos expression via disrupting class I HDAC activity. In CRC patients, butyrate negatively correlated with tumor xCT expression and positively correlated with c-Fos expression. Finally, butyrate was found to boost the pro-ferroptotic function of oxaliplatin (OXA). Immunohistochemistry data showed that OXA non-responders exhibited higher xCT expression compared to OXA responders. Hence, butyrate supplementation is a promising approach to break the ferroptosis resistance in CRC.
